ELMER H. LORING, OF W'OROESTER, MASSACHUSETTS, ASSIGNOB TO THE LORING 8: BLAKE ORGAN COMPANY, OF SAME PLACE.

TREMOLO FOR REED-ORGANS.

SPECIFICATION forming part of Letters Patent No. 292,439, dated January 22, 1884:. Application filed February 19, 1883. No model.)

To all whom, it may concern:

Be it known that I, ELMER H. Lonme, of Vorcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Tremolos for Reed-Organs; and I declare the following to be a description of my said invention sufficiently full, clear, and exact to enable others skilled in the art to which it appertains to mak and use the same, reference being had to the accompanying drawings, which form a In the references, A indicates the reed board; B, the bellows; G, the bellowsboard, and D the wind-chest.

E indicates the tremolomotor, and F the tremolo-fan, both of which are of ordinary form and operate in the ordinary manner.

G indicates the manual, and H the bracepiece, which parts are also, together with the reed-action, arranged relatively in the usual manner.

The case of the motor E is made of the form shown, and is secured to the top of the reed-board A, holes a and I) being formed through the board A to correspond with the air-passages ab in the motor-case. A block, D, having an internal horizontal channel, a is fixed to the interior of the wind-chest beneath the motor E, and the hole a is extended through into the said channel of. Another hole, a is extended up into the rear end of the channel a at the back of the bellows 13, thus making an air-passage of peculiar form, which enters in an upward direction from the under side of the board 0, then extends horizontally forward, and thence upward into the motor-case E, as illustrated. By this form of the inlet-passage I avoid the whistling noise incident to the usual form of passage.

Beneath the opening b, within the windchest D, I arrange the valve I for governing the action of the tremolo. Said valve is hinged to the under side of the reed-board A, so as to swing downward, is provided with a closing-spring, I, as illustrated, and is operated by a pitman or rod, J that passes through the board A, and has its upper end connected with a lever, K, depression of which opens the valve I. Lever K is pivoted to the side of the motor-case at 7;. Its front end is provided with an inclined lug, K, against which works the cranked lever M, which is fulcrumed on the braceboard H and operated by the stop-pull I, so that when the pull is drawn out the lever K will be depressed (see dotted lines) and the valve I will be opened. hen the valve I is closed, the lever K rests against the side of the fan-shaft 1*", and acts as a brake for stopping and retaining the fan from action. The crank-lever M is furnished with a friction-roll for bearing 011 the incline of the lever K, as shown. This method of arranging the passages, valves. and valve-operating devices renders the mechanism very perfect and satisfactory in its construction and operation. It can be conveniently made and adjusted, and works smoothly, quietly, and without liability of deterioration by time and usage or the effects of climate.

It will be understood thatI do not claim the invention of the fan-tremolo or the motorwheel for operating the fan, the essential fea tures of my invention being in the manner of arranging the parts in connection with the wind-chamber.

Vhat I claim as of my invention, and desire to secure by Letters Patent, is

The tremoloaction, as described, provided with air-passages a a a a." and b b, arranged and located relatively to the reed-board A and bellows-board O, in the manner shown, in combination with the valve I, located within the windchest D, as and for the purpose set forth.

IVitness my hand this 16th day of February, A. D. 1883.
